Besides bitcoin, it must be said that ethereum is the most worth investing coin in the cryptocurrency market. To me, it would be a meaningless investment if anyone's portfolio doesn't have these top 2 coins.
People who do not invest in these 2 coins are mainly risk takers and want to get rich quick in the market. And that's a common misconception these days.
Actually the best choice for investment is Bitcoin, because Bitcoin always dominates the market. But we have to diversify our investments and
we can't just invest in one coin, it's too risky to do. Therefore the next choice is Ethereum, because Ethereum has always been under Bitcoin
for a long time. This means that compared to other altcoins, Ethereum is the best. So like you said in our portfolio we can't miss Bitcoin and
Ethereum, because the two coins are the best in the crypto world. Of the many projects created, not one project can beat Bitcoin and Ethereum.
That's why when a bear market like now it's better we focus on collecting Bitcoin and Ethereum, it will give us big profit in the future,
because we can see the track record of Bitcoin and Ethereum which can always recover and rise to new ATH prices every time a bull market comes.
